The Messmate Or Stringbark (Eucalyptus Tetrodonta F. Muell). 94. The Sturt Creek Mallee (Eucalyptus Odontocarpa F. Muell), Charles Austin Gardner

Journal of the Department of Agriculture, Western Australia, Series 4

THIS species was originally named by W. V. Fitzgerald from specimens which he obtained from near Pingelly in November, 1903.

The name accedens is from the Latin accedo—to approach or come near—and is here used in reference to the supposed close approach of the tree to the common wandoo (Eucalyptus redunca var. elata).

The Effect Of Wet Strength Resins On The Dimensional Stability Of Paper, Robert Carey Jr.

Paper Engineering Senior Theses

Introduction

For many grades of paper, dimensional stability is very important in order for the paper to serve its specific purpose. Included in this category are such papers as map paper, template paper, printing papers, and chart paper. Dimensional stability may be improved by subjecting the fibers to less refining, but strength and other properties suffer as a result. Thus, any material which could be added to the fibers to increase dimensional stability would be welcomed by the paper industry.

The purpose of this thesis is to establish whether a particular type of material, wet strength resins, will improve dimensional …

Influence Of Logging On Douglas Fir Beetle Populations, R R. Lejeune, L H. Mcmullen, M D. Atkins

The Bark Beetles, Fuels, and Fire Bibliography

All species of bark beetles of economic importance prefer to attack freshly-killed host material. Logging slash, wind-throw, and fire-killed timber provide ideal breeding grounds for bark beetles. A few species, mostly in the Dendroctonus group, are able to kill living trees. When beetles in the group, raised in preferred host material, cannot find any or enough freshly-killed trees, logs, or slash to enter, they may attack living trees. In the interior of British Columbia, infestations of the Douglas fir beetle can often be traced to logging disturbance.

The Influence Of Stock Surface Properties On Grease Resistant Films, John H. Deryke

Paper Engineering Senior Theses

Introduction

One of the main problems in applying a continuous film to a fibrous surface such as paper is that coating must cover fibers that lie in every direction. This produces a relatively rough mat, with some fibers protruding. The surface of paper varies, but all papers and board have a surface configuration resembling a range of mountains. In paper, the interstices can be loaded with fillers, but with boards, fillers are not practical due to the amount necessary. Thus, in coating board with a continuous film, the surface configuration of the board is this main determining factor of the …

Mycorrhizae Of Ponderosa Pine In Nebraska Grassland Soils, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

While the genus Pinus has been the subject of extensive mycorrhizal studies there are only a few scattered references to western yellow pine, P. ponderosa, and no detailed descriptive literature on the mycorrhizae of this species. P. ponderosa is indigenous to Nebraska and the one species most extensively grown in local nurseries for windbreaks and farm plantings. Similarly, there is little information on mycorrhizae in the Great Plains between the forested regions of the Mississippi River states and the Rocky Mountains. Because this predominantly grassland area is sparse in natural tree growth the individual tree as an ornamental or …

Differences In Picking Properties Between Casein And Soya Proteins, Shinya Takekawa

Paper Engineering Senior Theses

In this paper, the various picking properties are discussed at first, then in the experiment the fundamental differences between soya protein and casein in picking strength were studied.

Since it is considered that the penetration of the adhesives in a coating mixture into the base paper is important in picking, the picking strength of casein and soya protein were evaluated in functions of the beating level, sizing level and the amount of the adhesives. Whole experimental data were treated with the statistical method.

The results indicate that with the Wax test, the soya protein and casein have almost equal picking …

Cold Caustic Soda Pulping Of Eucalyptus Saligna, Tachipully A. Bhaskaran

Paper Engineering Senior Theses

A survey has been prepared covering the literature on the cold caustic soda pulping of Eucalyptus saligna. The survey was broadened to include pulping of all species of Eucalyptus by this particular process.

Experimental pulping of Eucalyptus saligna by the cold caustic soda process under a variety of conditions as well as pulping of aspen wood under one condition led to the following conclusions:

(a) Eucalyptus saligna is suitable for the manufacture of cold caustic soda pulp.

(b) alkali concentration of 30 grams per liter on full size chips of Eucalyptus saligna produces the best strength properties and fairly good …

A Quantitative Study Of The Effect Of Cutting & Fibrillation On Certain Paper Properties, Edwin C. Abbott

Paper Engineering Senior Theses

Introduction

From the time of the invention of paper about the year 105 by Ts'ai Lun, the process of beating the pulp as a preliminary to forming a sheet of paper has been recognized as of prime importance.

Early papermakers did not concern themselves greatly with theories; it was enough to know the process necessary to produce the various combinations of long and short, slow and free stocks according to the paper being made. When chemists began to enter the mills, however, their attention was naturally drawn to this important aspect of beating, and to the relationship between cellulose and …

Cold Caustic Soda Pulp From Aspen Wood Some Facts On The Material Dissolved By The Process, Ralph D. Herrick

The available literature on the cold caustic soda pulping process, the composition of aspen wood, the composition of spent liquor from other pulping processes, paper chromatographic methods suitable for the analysis of wood and pulp hydrolyzates, and the material removed from aspen wood by the cold caustic soda pulping process have been surveyed.

Aspen wood hydrolyzates were analyzed using n-butanol: pyridine: water solvent system by paper chromatographic methods. Cold caustic soda pulp was prepared using a two hour soaking period at 25°^c temperature, and a 24 gram per liter caustic soda solution with a wood to liquor ratio …

Use Of Dialdehyde Starch In Coating Color Formulation, Craig F. Panse

Paper Engineering Senior Theses

A literature survey was conducted to determine what work, if any, had been done on dialdehyde starch as a coating adhesive. As a result of the survey, it was decided that experimental work would be started with the hope of overcoming some of the difficulties which confronted previous investigators and investigating further the use of dialdehyde starch as an adhesive.

After experimental preparation and evaluation of the coated and aftertreated sheets, the following conclusions were formed:

1. The addition of ten percent borax buffered or bisulphite buffered dialdehyde starch to conventional oxidized starch increases the surface strength of the coating …

A Study Of The Relationship Between Compressibility And Printing Smoothness, Richard R. Teugh

Paper Engineering Senior Theses

This investigation seems to indicate that printing smoothness, although dependent upon both smoothness of the sheet and compressibility, is much more dependent upon the smoothness of the paper being printed. For the samples tested printing pressure required seems to be a function of the smoothness and the deformation pressure with the smoothness apparently most important.
